Abstract: ABSTRACT OF THE DISCLOSURE A furnace includes combustion chambers having burners to which are supplied fuel and air under pressure.  Below the combustion chambers is an elongate furnace chamber separated from the overlying combustion chambers by refractory plates which have a plurality of equally dimensioned and spaced through holes.  The pressure of the supplied air, the diameter of the holes and the distance between the plates and strip stock which is passed through the furnace chamber is closely controlled so that combustion is essentially completed in the combustion chamber and the combustion products are directed in jets through the holes on to the strip stock at which location the essentially laminar flow of the jets becomes turbulent.  The stock is thus heated by radiation from the apertured plates and by convection.

Abstract: DIGITAL SIGNAL TRANSMISSION METHOD                   ABSTRACT OF THE DISCLOSURE       Groups of primary multi-bit digital signals arranged in digital words are spaced apart in sequence and are interleaved with related groups of secondary multi-bit digital signals, each of which is derived from, and encodes substantially the same information as, one of the primary signals.  To minimize errors in processing signals, either the primary signals are delayed relative to the secondary signals, or vice versa, be-fore they are interleaved.  Cyclic redundancy check code sig-nals are derived for each group of primary signals and each group of secondary signals and are interleaved in sequence with the primary and secondary signals.  At a further stage in processing the signals, the checked code signals are ana-lized and the related pairs of primary and secondary signals, which have been brought back into coincidence, are checked to determine whether one or both of the primary and the secondary signals of each related pair has been processed without error.  If only one of the signals has been pro-cessed without error, that signal is selected for further processing.  If both signals have been processed without error a predetermined one of them is selected for further processing.           If neither one of them has been processed without error, the immediately preceding signal that was selected may be selected a second time.  In order to incorporate all of the signals in the most convenient format, the secondary signals may com-prise only the higher bit orders of the primary signals, eliminating some of the lower bit orders as containing un-necessarily detailed information.  The number of bits thus omitted preferrably causes a group of secondary signals plus the cyclic redundancy check code signals for that group and for the related primary group to equal the total number of bits of that primary group.

Abstract: ABSTRACT OF THE DISCLOSURE         A system is provided for heating and ventilating objects and spaces surrounded by an outer covering, e.g. rooms in buildings.  The system includes a heat pumping device for converting low-temperature energy to high-temperature energy useful for heating purposes.  The heat pumping de-vice includes a condenser and an evaporator.  The condenser as well as the evaporator of the heat pumping device are each divided into several series-connected sections operating at progressively or step-wise decreasing con-denser temperatures and progressive or correspondingly step-wise increasing evaporator temperatures.  The outer covering of the space or object to be heated contains an air inlet system and an air outlet system, each of the systems having several series-connected sections located at different dis-tances from the outer surfaces of the covering.  Thus the sections are sub-jected to different temperatures related to the temperature gradient through the outer covering.  The individual condenser sections are contacted with the air of corresponding sections of the air inlet system, and the individual evaporator sections are in turn contacted with the air of the outlet system. The inlet and outlet air systems are preferably in heat exchanging contact with each other within the outer covering.  The modified condenser and evaporator allow the heat pumping device to operate more efficiently. Moreover, this provides energy-saving heating and/or ventilating system.

Abstract: ABSTRACT   In a miniature concealable radio alarm transmitter to be worn on the person, a switch means to activate the transmitter. The transmitter is preferably flat in flat in shape, and includes a small battery which extends across the end of the circuit board. Two spring contact members extend adjacent each end of the battery, within has button-type terminals on its ends.  A soft sponge elastomer spacer is fitted between each contact member and its end of the battery.  The spacer has a central hole. Finger pressure against either spring member forces it toward the adjacent battery terminal to make contact therewith. To connect the battery to the circuit and energize the alarm transmitter, both spring members must be squeezed toward each other from opposite sides of the transmitter, making contact with each battery terminal.  It is thus difficult to accidentally activate the transmitter. The switch means comprises two switches in series. The whole device is preferably cased in a bag-like enclosure of soft flexible material with a cord adapted to be hung around the wearer's neck.
